FIELD OF THE INVENTION

The present invention relates to a device, system and method for identifying a property of an article.

The property may relate to the position of an article to enable the tracking and/or location of the article, particularly, although not exclusively, for the tracking and locating of luggage and other articles in transit.

This can occur when travelling by plane, train or boat or any situations were articles such as items or luggage is transported from one destination to another. However, the invention can be seen to be tracking any article, item or object, and identifying properties of articles other than, or additional to, position.

BACKGROUND OF THE INVENTION

Each document, reference, patent application or patent cited in this text is expressly incorporated herein in their entirety by reference, which means that it should be read and considered by the reader as part of this text. That the document, reference, patent application, or patent cited in this text is not repeated in this text is merely for reasons of conciseness.

The following discussion of the background to the invention is intended to facilitate an understanding of the present invention only. It should be appreciated that the discussion is not an acknowledgment or admission that any of the material referred to was published, known or part of the common general knowledge of the person skilled in the art in any jurisdiction as at the priority date of the invention.

When travelling by airplane for example, a traveler's luggage is susceptible to being misplaced or lost by the airline baggage handlers. Retrieval of baggage can be troublesome and take days, weeks, even months and in some cases the luggage may never be found at all. This can be very stressful for the person travelling, and sometimes items within the luggage cannot be replaced, or are extremely valuable.

Tracking and locating systems and devices for articles exist. Some systems and devices initiate tracking when a tracking sensor is set off by movement and are therefore limited to having some form of movement to initiate the tracking. Other tracking devices are too large/heavy—preventing them from use with smaller items. Also many of the devices used require lots of power as they are constantly emitting signals, again making them impractical in real life situations were extended battery life is a necessity.

Systems and methods have been disclosed to facilitate the tracking of items with the use of radio frequency identification (RFID). However these are only applicable when monitoring items over a limited radius, and are susceptible to electromagnetic interference.

SUMMARY OF THE INVENTION

One aspect of the present invention includes an identification system including an identification device and a communication device. The identification device is attached to an article and including a sensor. The identification device is configured to operate in a plurality of modes and configured to switch between modes of the plurality of modes based on one or more conditions of a surrounding environment sensed by the sensor. The identification device is configured to send data to a server. The communication device of a user of the identification system is configured to receive data including location data of the identification device from the server using short message service protocols or messages through a signaling channel.

Embodiments of the present invention provide an advantage over known systems and devices in that they may alert the user to the location of an article when it has not arrived at its intended destination. Alternatively, the tagged article's location may be requested by the user at any time other than when the article is in transit in an airplane so as to comply with international regulation of GSM usage on aircraft. In such instances, the position identification device will go into a standby or minimum functionality mode preventing interference with navigation devices. Furthermore, embodiments of the present invention may enable the owner of the article to direct updates of the position of the article directly to their phone or email without the need for third party tracking. A further advantage is that embodiments of the invention may reduce the time and cost associated with the location and retrieval of lost baggage. The data from the location positioning device can be shared with airlines or airline service companies to assist location of the missing articles at airports, for example, or other relevant authorities as appropriate.

The embodiment of the identification system of the invention herein described particularly relates to identifying a property of an article comprising its position or location. It should be appreciated that the invention is not to be construed as being limited to this property, and alternative embodiments of the invention may relate to identifying properties of an article other than, or additional to, position and location, including, for example, temperature, visible light or other environmental conditions, proximity, pressure, or motion/movement, or a combination of properties.

A position identification system 1 in accordance with the embodiment of the present invention comprises a position identification device in the form of a tag 12 which can be securely attached to or incorporated in an article 10. For example, the tag 12 can be securely and releasably attachable to an article 10 in the same way as a luggage label, or can be incorporated into the article 10, for example, in a handle or part of the article housing as appropriate.

The tag 12 includes GSM (Group System for Mobiles), CDMA (Code Division Multiple Access) and OFDM (Orthogonal Frequency Division Multiplexing) functionality in the form of a GSM/3G/3.5G/4G (WiMAX/LTE) modem which enables the tag 12 to communicate with a central server system 11 of the position identification system 1 via a GSM/3G/3.5G/4G (WiMAX/LTE) or CDMA cellular radio telephone network 2. Cellular radio telephone networks and the GSM/3G/3.5G/4G (WiMAX/LTE) and CDMA communications protocols are well known to persons skilled in the art and need not be described in any further detail herein except as is relevant to the present invention.

In the embodiment described herein, the tag 12 is intended to be used by a person travelling to locate the position and potentially track the movement of an article 10 such as a piece of luggage that may be lost in transit.

FIGS. 2A and 2B schematically illustrate an embodiment of the tag 12.

The tag 12 comprises a printed circuit board (PCB) 13 with a first PCB face 14 (see FIG. 2A) and a second PCB face 15 (see FIG. 2B) which are opposed.

The first PCB face 14 includes a subscriber identity module (SIM) card slot 16 into which a SIM card 17 can be inserted. The SIM card slot 16 secures the SIM card 17 in place for operation. The SIM card 17 also stores various other information, such as the service-subscriber key (IMSI) and contact telephone number for example, as is well known. The use of SIM cards is well known to persons skilled in the art and need not be described in any further detail herein.

The PCB 13 also incorporates a battery 18 or other suitable power source for providing power for operation of the tag 12, and a charging socket 19 arranged for coupling a charging device to the battery 18. In a preferred embodiment the charging socket 19 may take the form of a mini AB/micro AB/universal serial bus (USB) interface which enables the battery 18 to be coupled to an external power source 20 such as a laptop, or dc-power supply in a vehicle, etc. so that the battery 18 can be recharged as required. The charging socket 19 (mini AB/micro AB/USB interface) is also operable to facilitate updating of firmware on the wireless module using a software application that may be specifically developed for the position identification device. In an alternative embodiment, the battery can be a non-rechargeable battery or other suitable power source. In a further embodiment, applicable in situations where an animal is to be tracked, for example, or where the tag 12 is to be exposed to sunlight, the tag 12 also incorporates solar powered charging means to further sustain battery life/operation time. In further embodiments of the invention, other charging techniques and technologies may also or alternatively be used, such as induction charging.

A chip-set 21 is mounted on the PCB 13 and is coupled to an antenna 22, and a processor in the form of an embedded microcontroller 23 to provide the operation of the tag 12 as will be described in further detail below.

The communications chip-set 21 includes a radio frequency transceiver (not shown) and operates to perform the data communications for operation of the tag 12 using the radio frequency communications in accordance with GSM/3G/3.5G/4G (WiMAX/LTE) and CDMA protocols in the usual, known manner. In further embodiments, GPRS (General Packet Radio Service), third generation (3G) and fourth generation (4G) or LTE/WiMAX communication protocols are adopted.

The communications chip-set 21 also provides a means to perform such radio baseband functions as power management, signal amplification, signal filtering, frequency duplexing, advanced signal processing and data communication to the embedded microcontroller 23 and to the SIM card 17 and other wireless functions including Bluetooth™, Wi-Fi, WiMAX, ZigBee communication, and other digital processes.

The antenna 22 is operable to transmit and receive radio frequency (RF) communications signals to and from the radio network 2 which are coupled to the chip-set 21 in the usual, known manner. In a preferred embodiment, the antenna 22 can be in the form of a flexible strap that can be used to secure the tag 12 to the article 10—see FIG. 3. Using a helical based antenna wound as part of the attachment mechanism is advantageous as it increases antenna efficiency, signal sensitivity and reduces RF power consumption.

In the present embodiment, the microcontroller 23 is a commercially available microcontroller. The microcontroller 23 stores software and location information from the SIM card 17, and firmware pertinent to the operation and function of the tag 12 in any suitable manner known to persons skilled in the art. The microcontroller 23 is coupled to the communications chipset 21 by a hard wired connection (not shown) or any other suitable wired or wireless connection. In further embodiments, the communications chipset incorporates such protocols as GPRS (General Packet Radio Service), third generation (3G) and fourth generation (4G) protocols for communicating means.

A display 24 is provided on the second PCB face 15. In a preferred embodiment the display 24 is an e-paper or liquid crystal display (LCD) and is operable to display, via a user interface, article identification information such as the user name and arrival destination and user contact flight number—as illustrated schematically in FIG. 4.

This information is uploaded to the microcontroller 23 by the user using the central server system 11 as will be described in further detail below. Once uploaded to the tag 12, this information can be displayed on the display 24 as shown in FIG. 4. Thus, the tag 12 acts as a luggage label which enables anyone who finds the article 10 to contact the user. Other information or data may also be displayed, such as a battery indicator indicating an amount of charge of the battery 18 and/or an indicator showing successful connection to cellular network, for example.

The second PCB face 15 also further comprises an alert means or indicator in the form of a light emitting diode (LED) 25, visible on both sides (i.e. the first PCB face 14 and the second PCB face 15) of the PCB 13, and a sensor or detector in the form of a light sensor 26, operable on both sides (i.e. the first PCB face 14 and the second PCB face 15) of the PCB 13. The light sensor 26 is mounted horizontally with a light pathway from either side of the tag 12. In alternative embodiments of the invention, light pathways may be provided on both sides of the PCB 13.

The LED 25 is operable to indicate the status of the article 10. In this embodiment, the LED 25 is operable to illuminate if the article 10 is determined to be missing.

The tag 12 is arranged to switch between a first, a second and a third mode, state or method of operation—a “reception” or “normal mode (receive and transmit radio data)”, a “disabled/lock off” or “minimum or minimal functionality mode (no reception or transmission of radio data)” and an “alarm or alert mode (receive and transmit data, the LCD of the display means 24 activated and the LED illuminated)”, respectively.

In the minimum functionality mode, the tag 12 is disabled from wireless communication via the antenna 22 and is placed into minimum functionality mode turning off all non essential electronic circuits to conserve battery life. When the article 10 is travelling by airplane, for example, wireless RF communication devices may interfere with the navigation systems of the airplane, and it is therefore imperative that the tag 12 does not use RF communications at this time. When in the cargo hold of an airplane it may be necessary to make sure that the tag 12 is in minimum functionality. A further benefit of switching the tag to the minimum functionality mode, is that when in storage compartment it serves to conserve battery power. In a further, fourth mode of operation—“flight” or “travel” mode the tag 12 can be set by a user to operate in the hereinbefore described minimal functionality mode for a period of time. The period of time may be predetermined or prescribed.

When the tag 12 is in normal functionality mode it is operable to send and receive data and respond to any location requests via the position identification system 1 as described in further detail below.

Switching between the minimum functionality mode and normal mode is activated by means of the sensor 26.

In one embodiment, the sensor 26 includes a light sensitive resistor which is operable to determine when ambient light in the vicinity of the tag 12 falls below a predetermined threshold and, at such time, the sensor 26 is operable to switch the tag 12 to the minimum functionality mode. The sensor 26 generates and sends a signal to the microcontroller 23 to place all non-essential electronic components of the tag 12 into a low power mode and to disable the RF communication on the GSM Controller which is incorporated into the communication chip-set 21. To reduce the risk of fire, aircraft cargo holds are not lit after the cargo hold doors are closed so in this way, when the surrounding environment goes dark, the tag 12 is switched to the minimum functionality mode. In an embodiment of the invention, the tag 12 is operable to automatically “wake up” and enter the reception or normal mode of operation once a condition or event is satisfied, such as once every 24 hours after first detection of light, irrespective of light conditions, for example. Such operation advantageously allows for location of tagged articles (such as bags) that have been permanently stored in a dark location.

In should be appreciated that the invention is not limited to the indicator and sensor described, and in alternative embodiments the property identification device may comprise a plurality or set of indicators operable to provide an indication of a plurality of events or conditions. Additionally, or alternatively, the property identification device can comprise a plurality or set of sensors or detectors operable to sense and gather sensor data or information relating to properties (property identification data) and parameters of and/or associated with the property identification device, the article, and/or the property identification system additional to or instead of position identification data, and to communicate the detected sensor data to a processor of the property identification device (such as the microcontroller 23) and/or another device, such as the central server system 11, for processing. On the basis of the processing of the received sensor data, the processor (under control of software) is operable to determine or identify the property and/or whether an event or condition has occurred and control operation of components of the property identification system accordingly to initiate an action corresponding to the determined event or condition. The initiated action may comprise, for example, activating an appropriate indicator, or changing the state or mode of operation of the property identification device and/or another component of the property identification system from one state to another state.

The abovementioned processing of the data undertaken by the relevant processor may be controlled by an analytical software application operable to determine on the basis of the data whether a prescribed event or circumstance has occurred (such as a temperature exceeded or deviation of an article or item from a prescribed path) and to control components of the position identification system 1 accordingly to initiate appropriate action(s).

In one embodiment, a sensor is provided that includes a mechanism to detect fluctuation of wireless signal strength and neighboring cellular information (i.e. radio frequency (RF) signal strength changes or fluctuations) and from this data the microcontroller 23 is operable to determine whether the tag 12 is, for example, moving constantly at selected speeds, accelerating or stationary, and to control the state or mode of operation of the tag 12 accordingly—i.e. to automatically switch from one state or mode to another. Such a sensor operation advantageously allows for the tag 12 to be switched to the minimum functionality mode when motion is detected (i.e. when an aircraft, for example, is in taxi, takeoff or landing operations as a moving aircraft will be subject to changing RF signal strength as it moves towards, away from, or across an RF signal source) and switched to the normal mode when no motion is detected (i.e. the RF signal strength is constant rather than changing). Accordingly, changes in wireless signal strength are used to determine if the position identification device is moving or stationary and switched on/off accordingly.

In further embodiments of the invention, the set of sensors include temperature sensors or thermometers so that, in addition to or instead of location data, temperature information or data (or other properties or storage parameters) can be sensed and communicated, either on request or automatically if set parameters are breached/exceeded, and identified and appropriate action initiated by the processor based on the temperature information. Temperature sensitive goods including pharmaceutical agents, human tissue and vaccines as well as other commodities such as meat and fish requiring transportation under strict temperature controls could be monitored during transportation by a property identification device of the invention having such a sensor and if set parameters are breached the property identification system operable to determine the occurrence of the same and act appropriately, such as generating and delivering an information communication in the form of an SMS, email or website alarm to a communication device of an owner of the goods—thereby enabling remedial action to be taken before the goods are spoiled. The information delivered via the communication may include the actual temperature of goods in transit, in addition to their actual position or location if such property is also being sensed.

Pressure and proximity sensors and other telemetry sensors may also be used to gather data and information in alternative embodiments of the invention. In an alternative embodiment, the tag 12 (or indeed a plurality of tags 12) could be simultaneously switched to the minimum functionality mode using a remote device (not shown), for example, using wireless communication.

In a preferred embodiment the tag 12 will be encased in a robust housing 27. The robust housing 27 can be of any suitable type and configuration. It should be made to be able to withstand extreme weather conditions that it may encounter allowing the tag 12 to operate correctly when in those conditions.

In a preferred embodiment of the tag 12, the housing 27 may be in the form of a convex-shaped housing with a transparent window so that the display means 24 is visible through the housing window and there is a light pathway to the light sensor 26. The housing 27 has a convex-shaped profile to ensure that tag 12 cannot be pushed flat against the surface of a suitcase or other surfaces which might prevent light getting to the sensor means 26, which might inadvertently cause the tag 12 to switch to the minimum functionality mode. Alternatively, the sensor 26 may have light pathways from either side of the tag 12.

In an integrated embodiment of the tag 1, the SIM card 17 and the microcontroller 23 are built inside the tag 12, so are not visible to the user. Other than these features the integrated embodiment of the tag 12 is as previously described.

The tag 12 is in communication with the central server system 11 via a cellular radio telephone network 2, which in this embodiment is a GSM network.

The central server system 11 comprises a CTI (Computer Telephony Integration)/IVR (Interactive Voice Response) server 40, a call manager server/PSTN gateway 41, a database server 42, a web server 43, a user directory server 44 and an SMS (Short Message Service) application server 45. CTI and IVR servers—which provide computer telephony integration and voice response to callers—are well known to persons skilled in the art and need not be described in any further detail herein.

The central server system 11 is illustrated schematically in FIG. 1.

The call manager server 41 is operable to receive calls from users of the position identification system 1 via fixed line telephones 48, and/or cellular radio telephones 47.

The database server 42 is arranged for data communication with external third party databases 49, for example, hosted by an airline, airport operator or travel company. The data communication can be implemented in any suitable known way, for example via a wide area network such as the Internet or a local area network.

The web server is arranged to provide web-based access to users of the position identification system 1 via the Internet 51 from remote terminals 50 comprising communication devices such as computers, personal digital assistants, internet-enabled cellular radio telephones and such.

The user directory server 44 is used to store account details of users of the position identification device, including such details as name, passwords, Personal Identification Number, and serial numbers

The CTI/IVR server 40, the call manager server 41, the database server 42, web server 43, and user directory server 44 are all in database communication with the SMS application server 45.

The SMS application server 45 enables communication with the tag 12 as will be described in further detail below and provides for the functionality of the position identification system 1 at the central server system 11.

The SMS application server 45 is in data communication with an SMS service center 46 provided as part of the cellular radio telephone network 2 by the network operator. The operation of SMS service centers and the operation of SMS services are well known to persons skilled in the art and need not be described in any further detail herein. When the tag 12 is in the minimum functionality mode of operation messages are stored on the SMS application server 45 and re-sent at regular time intervals until expiry of a prescribed or selected time period. In this manner, once the tag 12 changes from minimal functionality mode to reception or normal mode the massage will finally be delivered.

A user is allocated a tag 12 for use in tracking the position of the article 10 to which it is securely attached.

This can be done using one of the remote terminals 50 via the Internet 51 and the web server 43. Alternatively, this may also be done via telephone 47, 48 using the interactive voice response (IVR)/computer telephony integration (CTI) server 40 or via the call manager server 41 in any suitable known way. The information is then stored on the database server 42. Alternatively this may be done via cellular telephone 47 using a central SMS number. It is the database server 42 that stores this information.

Third party service providers such as airlines may provide a means to upload travel details to the database server 42 from third party database server 49.

In a further embodiment data may also be inputted by way of Bluetooth™, Wi-Fi, WiMAX, ZigBee communication or some other wireless means.

The SMS application server 45 is then operable to upload the article identification data to the microcontroller 23 and the tag 12 for display on the LED display 24. This article identification data comprises information about the user and may include, for example, the user's contact details and intended destination of the article 10 as mentioned above.

Before transit, the tag 12 is placed in the normal mode as described above.

The SMS application server 45 sends specific commands to the communications chip-set 21 to place the tag in the normal mode.

Once the article 10 is in transit, the tag will remain in the normal mode until such time as it is loaded into a cargo hold of the airplane, or other such transport mode, where the tag 12 will switch to the minimum functionality mode in response to the sensor means 26 detecting that the lights in the cargo hold are switched off.

In another embodiment of the invention the plurality of tags 12 may be temporarily switched off by central remote control as discussed above. This mechanism disables both radio functionality and puts the tag 12 into minimal operating mode and overrides all other operating modes of the device.

If the article 10 arrives at its destination, then the user can switch off the tag 12 through the central server system 11 or other appropriate means when the user takes possession of the article 10.

The user can program multiple flight information (multiple itineraries) into the database server 42. Therefore a multi flight journey can be programmed into the database server 42 and transmitted to the position location device 12 after each individual flight via the application server 45 to the tag microcontroller 23. This new destination information is then up-loaded to the LCD screen of the display means 24.

If the article 10 does not arrive at its intended destination, then the user will be advised of its destination, as follows.

Location of the article 10 can be determined by contacting the tag 12 to respond with its location. The user can manually activate alert mode upon request. Following this the tag 12 will activate its alert means 25 and activate the LED to illuminate as described above. This mechanism will allow baggage handlers or the user for example to identify luggage quickly.

When a user wishes to query the location of the article 10, the user calls the central server system 11 in the usual way and as described above in respect of the uploading of information to the tag 12.

In response to a user request for the location of the tag 12, the SMS application server 45 is operable to poll a unique mobile subscriber integrated services digital network (MSISDN) number allocated to the SIM card 17.

The SMS application server 45 sends a query to the position identification device using the MSISDN number to extract the location information from the SIM card 17.

The details of the MSISDN are stored in the database server 42 and are retrieved by the SMS application server 45 from the database server 42 to poll the SIM card 17.

The SMS application server 45 sends a command string using standard SMS format to the position identification device in order to poll the information on the SIM card 17 and microcontroller 23.

On receiving the location request i.e. the poll from the SMS application server 45, the tag 12 is operable to poll the nearest operable base transceiver station (not shown) within the cellular radio network 2 to determine the location area identifier (LAI) and cellular identifier (CellID) for the SIM card's location and to store it in the SIM 22 and the microcontroller 23. The use of the LAI and CellID to determine the location in which a SIM card 17 is located is well known to persons skilled in the art and need not be described in any further detail herein.

Under control of software built into the microcontroller 23, the tag 12 is operable to send an SMS status message to the SMS application server 45 containing the LAI and CellID information. The SMS application server 45 is then operable to map the LAI and CellID against specific destination information, such as the nearest airport or specific airport terminal, stored in the database server 42 thus determining a specific location for the article 10.

The described embodiment of the position identification device determines its location based on strongest received signal strength indication (RSSI) (being the closest BTS station to the airport). The central server system 11 includes a database for storing data on local area identifiers and corresponding location information, and the central server system 11 is operable to determine the location information from the local area identifier. Alternatively the central server system database may also store data from the position identification devices and users associated thereto.

The SMS application server 45 is then operable to create an SMS message, email or IVR to include details of the location as previously determined, which is then sent to the user who initiated the location request i.e. the user. This SMS message is sent to the user who will then be able to know where the article 10 is located.

In another embodiment, the SMS application server 45 can be operable to send an email in addition or instead of with the required information. User emails, addresses and cellular radio telephone numbers are all stored on the database server 42.

At the same time, the microcontroller 23 is operable to send a signal to the LED 25 to cause it to illuminate as described above.

In the second embodiment of the invention, the tag 12 is operable to automatically initiate a check on its position and compare it to the intended destination, rather than waiting for a location request from the central server system 11.

In this instance, when the position identification device is removed from the hold of an aircraft and automatically switches to normal mode, the microcontroller 23 and the communications chip-set 21 is operable to determine the LAI and CellID and to send an SMS status message to the SMS application server 45 as before. The SMS application server 45 is then operable to determine the location as described above and to compare it (the determined actual location) with the expected/desired destination (which will have been uploaded by the user initially and will be stored on the database server 42). If the two do not match, the position identification system 1 is operable to alert the user of the actual position of the tag 12 (and therefore of the article 10 to which it is connected) in the same way as before. In addition, the alert means 25 is activated to indicate to people in the vicinity of the article 10—such as airline and baggage handling staff—that the article 10 is missing/not at its intended destination.

Each tag 12 will also have a unique IMEI/IMSI number in the same way as all GSM mobile devices. This can be represented as a barcode on the device. This can be scanned by airlines or other third parties and compared with known databases that store this data. This can also assist in locating owners of lost articles or for inventory information as the IMEI is linked to GSM operator databases, mobile manufacturers and retailers.

In another embodiment of the invention, the tag 12 can include GPS capabilities to determine location by means of GPS data. This can then be sent in the SMS status message to the SMS application server 45 and used appropriately.

If the SMS card 17 is removed from the tag, then the tag 12 is unusable.

In an advantageous embodiment of the invention, the tag 12 incorporates a lock in the form of a mechanical barrel lock or an electro mechanical securing means or fastener 52 for attaching the tag 12 to the article 10, illustrated in FIGS. 5a, 5b , and 6 of the drawings. Alternative embodiments of the lock can be used independently of the tag 12, for performing a locking/securing/attaching function in other applications.

The fastener 52 comprises a first processor which in this embodiment is in the form of a lock microcontroller 54 operably connected to an actuator in the form of an electromagnetic driver circuit 56 operably connected to a ferrite core 58 having a coil 59. The microcontroller 54 is in communication with the communications chip-set 21 of the tag 12, such that instruction messages received by the communications chip-set 21 by way of SMS can be processed by the lock microcontroller 54. If the communications chip-set 21 receives an SMS instruction message containing an “unlock” password, such as the user's personal identification number, it will be processed by the microcontroller 54 as an unlock code to unlock or disengage the fastener 52 as further described below.

The microcontroller 54 may be a separate microcontroller. In a preferred embodiment, the fastener 52 uses the existing microcontroller 23 of the tag 12.

The electromagnetic driver circuit 56 is operable to receive operating instructions from the microcontroller 54 and to relay these to the ferrite core 58 and coil 59 by way of electrical signals.

The ferrite core 58 is in contact with first biasing means or biaser which in this embodiment comprises a spring 60 operably coupled between the ferrite core 58 and first engagement means or engager in the form of a pin 62. The coil 59 is wound around the pin 62 and the ferrite core 58 to induce magnetism when the core 58 is energised. The pin 62 is slidably retained in a guide channel 63 extending from the ferrite core 58 and opening into a recess 65 provided in the housing 27 of the tag 12 and bounded by a support 70. The pin 62 is moveable between a first, unlocked, position in which it is completely retained within the guide channel 63, with the spring 60 compressed between the ferrite core 58 and the end of the pin 62 proximate thereto, and a second, locked, position in which the end of the pin 62 remote from the ferrite core 58 extends into the recess 65. In the second position, the spring 60 is uncompressed, i.e. is extended, between the ferrite core 58 and the end of the pin 62 proximate thereto.

A second engagement means or engager is provided in the form of a connector head 66 removeably receivable within the recess 65. The connector head 66 is moveable from a first, unlocked, position in which it is free to move within and exit the recess 65, and a second, locked position, in which the end of the pin 62 remote from the ferrite core 58 extends into the recess 65 and a locking groove 67 of the connector head 66 to lockingly engage therewith.

The connector head 66 is operably connected to a wire cable 68, via which the tag 12 and fastener 52 can be attached to an article, and is bounded by the conductive support 70 when received in the recess 65. The conductive support 70 is further connected to a second processor. In a preferred embodiment the wire cable 68 incorporates an antenna such as the antenna 22 described in FIG. 2 a.

A second biasing means or biaser comprising a leaf spring 64 is also provided, extending parallel along the guide channel 63 such that a moveable end thereof extends into the recess 65. The leaf spring 64 assists in retaining the pin 60 in place in its first position and preventing it from moving unintentionally into the second, locked, position. In this regard, the leaf spring 64 is moveable from a retaining position, in which a retaining projection 69 thereof is received within a retaining notch 71 of the pin 62 to hold the pin 62 once in the first, unlocked, position and an unretaining position in which the retaining projection 69 is removed from the retaining notch 71. Insertion of the connector head 66 into the recess 65 an operative distance causes it to abut the moveable end of the leaf spring 64, and move it from the retaining position to the unretaining position when inserted beyond the operative distance.

On receipt of an SMS instruction message containing an “unlock” password by the communications chip-set 21, the lock microcontroller 54 instructs the electromagnetic driver circuit 56 to energise the ferrite core 58 and coil 59. Energisation of the ferrite core 58 and coil 59 causes the pin 62 to be attracted thereto via induced magnetism, slidably moving it into the first position and compressing the spring 60. Energisation of the ferrite core 58 is time limited to conserve battery power.

In this position, the connector head 66 is moveable within the recess 65. Without the restraining pin 62 holding the connector head 66, the force of the leaf spring 64 is sufficient to cause the leaf spring 64 to straighten and push the connector head 66 retrograde in the recess 65, causing the projection 69 to locate into the retaining notch 71 and locking the restraining pin 62 in the open position with the spring 60 compressed. This action also allows the connector head 66 to be removed from the recess 65 and the tag 12 unsecured from/or secured to the article 10. As the connector head 66 is withdrawn from the recess 65 so that it no longer extends beyond the operative distance, the leaf spring 64 moves to a retaining position in which the retaining projection 69 thereof is received within the retaining notch 71 of the pin 62 to hold the pin 62 in the first, unlocked, position.

To lock the fastener 52, the wire cable 68 is looped around or through an appropriate portion of the article 10 (such as a handle thereof). The connector head 66 is inserted into the recess 65 beyond the operative distance such that the locking groove 67 aligns with the guide channel 63, and the moveable end of the leaf spring 64 is abutted and moved from the retaining position to the unretaining position. In this manner, the retaining projection 69 of the leaf spring 64 is withdrawn from the retaining notch 71 of the pin 62 and it is free to move from the first, unlocked, position to the locked position.

As the ferrite core 58 and coil 59 is not energised, the pin 62 is no longer attracted thereto, and the spring 60 expands to move the pin 62 to the second, locked, position. In this position, the end of the pin 62 remote from the ferrite core 58 extends into the recess 65 and locking groove 67 of the connector head 66 to lockingly engage therewith, and thereby secure the tag 12 to the article 10.

As described above, the conductive support 70 is operably connected to a second processor which in this embodiment is in the form of a microcontroller 72. In addition to providing a strong support around connector head 66, the conductive support 70 completes an electrical circuit connecting all components within the securing means 52. The microcontroller 72 is operably connected to the communications chip-set 21. If the microcontroller 72 detects that the wire cable 68 is broken or detached without proper instructions, or the circuit formed by the components is otherwise broken, it will instantly send instructions through to the communications chip-set 21 to send an SMS to the user or nominated authority with the position location of the tag 12 at that instant.

In a further embodiment, the connector head 66 may be under tension by another biasing means or biaser which may be a spring which is held in bias when in the locked position and further forces the connector head 66 when disengaged to retract and release the tag 12. The leaf spring 64 may also perform such a function if appropriately tensioned. In a further embodiment the second engagement means or element may be operably connected to the alert means 25, thus allowing an alert signal to the user to be generated once the fastener 52 is unlocked, prompting the user to retract the connector head 66.

In a further embodiment, the fastener 52 may also receive detachment instructions by way of Bluetooth, infrared or such wireless controls from a control unit it is in sync with.

In another embodiment of the lock, the microcontroller 54 is operable to process an SMS instruction message containing a “lock” password received by the communications chip-set 21 as a lock code instruction and lock the securing means.

Variations are possible within the scope of the present invention. For example, the tag 12 can determine its location using known triangulation techniques rather than determining the LAI, or other positioning methods, such as hybrid methods (including Assisted GPS); Time Difference of Arrival (TOA) methods; and/or Angle of Arrival (AoA) methods.

Furthermore, any suitable communication protocol can be used to facilitate communication between any subsystems or components of the position identification system 1, including wired and wireless and an SS7 (Signaling System 7) signaling channel, as are well known to persons skilled in the art and need not be described in any further detail herein.

The tracking and locating system and method of the described embodiment of the present invention is not limited to such tracking and locating, however. In alternative embodiments it may be used to track and locate any person, animal, freight, vehicle, parole prisoner, children and other moving or movable objects. These could all be tracked or located by use of alternative embodiments of the present invention.

As described previously, in embodiments of the invention the position identification device can be incorporated into the article itself and in one embodiment is built into a laptop computer or similar devices.

As also described, properties other than, or additional to, position and location may be identified in alternative embodiments of the invention.

It should be further appreciated by the person skilled in the art that variations and combinations of features described above, not being alternatives or substitutes, can be combined to form yet further embodiments falling within the intended scope of the invention.
